HTTP4 Component and encoding message body

[Andrew Thorburn]

When sending a message to an HTTP4 Endpoint, will the content of the
message body be automatically encoded? e.g. The spaces replaced with %20
and whatever else is necessary to ensure that the POST request isn't
mangled on the other side.

I can't see anything in the documentation to tell me whether this is
handled automatically or whether I need to convert it myself. At this stage
it looks like it is handled automatically, since I don't see anything
telling me otherwise, but I'm not sure.

More to the point, how do I pass multiple parameters as the body? e.g. I'd
like to have a Web Service call, transform whatever was passed to the web
service to parameters for an HTTP POST request, and pass them to the HTTP4
endpoint.

e.g.

Given a Web Service Request,

<soap:Body>
  <request>
    <p1>value1</p1>
    <p2>value2&amp;value2.1</p2>
  </request>
</soap:Body>

have the body of the POST request be: "p1=value1&p2=value2%26value2.1". My
request is a little more complex than that, but not by much. Hopefully what
I want makes sense?

Thanks,
